        <footnote id="F3">These shares were granted as performance share units and vest one hundred percent on August 12, 2022, with an additional one year holding period (4 years total until settlement), subject to acceleration and cancellation upon the occurrence of certain events.  Each performance share unit converts into the number of shares of common stock determined by applying the TSR multiplier to the number of units vesting on the third anniversary of the date of grant.   The TSR multiplier is based on relative TSR performance versus peers over the three year vesting period. The peer group is the S&amp;P Small Cap 600 Industrial Index, of which EnerSys is a member, and consists of approximately 100 companies. The minimum TSR multiplier is 0% and the maximum TSR multiplier is 200%.  These shares represent the performance share units granted, assuming a TSR multiplier of 100%.</footnote>
